Gladia is a speech-to-text API platform that records, transcribes and enriches audio in 100+ languages, helping developers build meeting assistants, voice agents and contact-center products.
About
Gladia is an audio infrastructure platform that converts spoken conversations into structured, usable data through a single API. It addresses a common problem for teams building voice products: inaccurate transcription corrupts everything built on top of it, from meeting notes to CRM records. Gladia handles the full pipeline — capturing audio, transcribing it, enriching the transcript, and routing the results to other systems.
The platform supports both asynchronous batch transcription and real-time streaming, covering more than 100 languages with automatic language detection. Developers send audio via WebSocket streaming, REST upload, or live microphone input, using SDKs for Python and Node.js or direct API calls. Beyond raw transcription, Gladia offers speaker diarization, entity detection, sentiment analysis, PII redaction, and an audio-to-LLM pipeline, plus native integrations with tools such as Zoom, Google Meet and Microsoft Teams. The company reports over 26 million hours of audio transcribed and serves more than 300,000 developers and 2,000 enterprise teams.

Who It's For
Gladia is built primarily for developers and product teams adding voice capabilities to software. Typical users include teams building AI meeting assistants and note-takers, contact-center-as-a-service (CCaaS) platforms, voice agents, and content or media workflows that need searchable transcripts. It also suits startups — a Startup Studio program offers $3,000 in credits over 12 months plus a dedicated field developer engineer — and enterprises that need EU data residency, compliance certifications and custom models for large transcription volumes.
